A few weeks ago, NSIDC put out this press release, claiming that 5+ year old ice is at its smallest level on record.

ice at least 5 years or older, is at its smallest level in the satellite record, representing only 3 percent of the total ice cover

The press release included the map below. This is a new style map which they just started in week 39 2015. The map below is for week 41 2015. All of their previous 1984-2015 maps have been deleted from their archive.

NSIDC has deleted the original graphs, but seem to have forgotten to get rid of the copy.

Here is where they get in trouble. Besides deleting data, NSIDC also deleted a lot of older ice when they switched maps. Note inside the circle how the red five year old ice has disappeared in their new maps.

The alterations are huge, and shown in the graph below. NSIDC deleted almost half of the five year old ice when they switched to the new maps. They also deleted about a third of the four year old ice, and some of the three year old ice.

Referring back to the top graph again, it becomes clear what they are up to. Had they used the same map set for the 2016 data as they did for all the other data in the graph below, 2016 would have had the most 4+ ice since about 2009. The graph below is junk science, useful only for propaganda.

It is bad enough that they switched data without telling anyone and used it to generate meaningless propaganda, but they also deleted all of the 1984 to week 36 2015 data from the disk. Fortunately they missed one map, which is the smoking gun. If the old data was that bad and needed to be deleted, then any comparisons made between the old and new data are extremely misleading- which is exactly what NSIDC was doing. They tracked that region of five year old ice for several years, and then suddenly decided it didn’t exist. Unbelievable.

AGW has never had a solid foundation and it was always anticipated ; when the “predictions” for melting weren’t there to be found… the lies & propaganda will make it so.! I still believe there will be a day of reckoning for extreme “Warmist” organisations ; the sooner the better…

Congratulations to Chris71 and to you again, Steven, congratulations for having the analytical ability to detect and the courage to report FALSE INFORMATION disguised as “CONSENSUS SCIENCE!”

On 4 JULY 1776 the Declaration of Independence proclaimed that we were endowed by our Creator with inalienable rights to establish, alter or abolish governments to protect our right to enjoy life, liberty and the pursuit of happiness.

Less than 170 years later, on 24 OCT 1945, our independence as a nation was compromised by the decision of frightened world leaders to unite nations and national academies of sciences to “save the world from nuclear annihilation” by hiding the source of energy in atomic bombs.

The National Academy of Sciences guided federal research programs over the past seventy years (1946 – 2916) to prevent the public from learning that;

1. The source of energy in atomic bombs is indelibly recorded in exact rest masses of the 3,000 types of atoms that compromise all matter, as Aston explained in his Nobel Lecture in DEC 1922, and

2. The Creator & Sustainer of every atom, life and planet in the solar system uses the same source of energy as atomic bombs and has this physical appearance:

Public anger this election year at mainstream Democrats and Republicans, who worked
together to deceive the public for decades, means the above empirical fact may leak past the “Orwelluan Ministry of Scientific (UN)Truths,” especially if angry Democrats and Republicans join forces in a Trump-Sanders sweep of the November election!

CORRECTION: The National Academy of Sciences guided federal research programs over the past seventy years (1946 – 2016) to prevent the public from learning that: . . .

It does not matter who is elected President, if the US National Academy of Sciences retains control of United States policies (as former President Eisenhower warned might happen in his farewell address to the nation on 17 JAN 1961

has anyone contacted them for an explanation of this change ? climastrology is a funny old game, rather than use the same method to create a data set it seems every time a metric is not playing ball they just measure it a different way or adjust the measurements to suit the narrative.

whatever it is they are doing it sure doesn’t meet any normal definition of science. once again thanks to tony for highlighting these issues.

You know this is really quite silly. Since the data is obtained using passive microwaves and weather models there’s no reason why they couldn’t have just issued the younger sea ice age data to begin with. The fact that the data has changed may simply reflect a re-analysis based on recalibration or simply erroneous inputs into the model.

If the variability within each cluster is quantified and taken into account by using multispectral analysis, in addition to improving the capability of classifying ice by age, information about ice thickness and surface characteristics might also be obtainable.

yep, lots of old ice around about the end of the last period the amo was in the cool phase jim . as it is moving into the next cool phase at the moment, i wonder how long it will take to build back up to that level or maybe a bit higher or lower.

probably the 30 or so years it took to get to the high of the late 70’s from the 40’s.

ps, do you have the original version , just for a comparison🙂. sometimes things get missed out in climate science when changes are made to visual depictions of various phenomena ,accidentally of course😉

Accidental changes such as adding bright yellow circles and giant text you mean?

Assuming that you’re addressing yours truly, and referring to version 3 of the NSIDC’s Arctic sea ice age map for week 41 of 1984 it’s where you’d expect to find it. See the sea ice age section of the NSIDC web site.

How about you make some changes to your web site and start telling the whole truth about Arctic sea ice.

Or are you too much of a LAIR and a COWARD to do so.

1984.. just near the trough of the AMO, and at the end of a climb out of the COLDEST period in the last 10,000 years… of course there was more sea ice than basically the whole of the current interglacial. So what. Even now after a bit of natural warming from the AMO cycle, the Arctic sea ice level is still very high.

You know that, but refuse to say so, because you know your AGW swillers from Exeter Uni would not like it.

Gavin and Tonm would be proud of NS-DIC.. find another way to “ADJUST” the data
odd that its ALWAYS in support of the AGW FRAUD.

Speaking of FRAUD, how is that pathetic LYING CON of a web site going ?

You know, the one whose owner is TOO COWARDLY to indicate the real Holocene history of regular ZERO summer sea ice for most of the first 7000 years, and its too MIS-INFORMED to mention that the reason there is STILL SO MUCH Arctic sea ice is because we are still very much at the cold end of the interglacial.

And isn’t it obvious that four and five year ice is NOT going to disappear quickly. This is clearly fraudulent. It takes the blindest of the blind to NOT see this. (Or any CAGW believer) You can try to make all the excuses you want, but if you CANNOT explain how four and five year ice could so rapidly become much thinner, then you are just lying.

They were either wrong or lying before when they claimed there was so much multi-year ice, or they are wrong or lying now when they claim there is so much less. Either way you cut it, there is error or lies or both. And considering that only the claim that there is less multi-year ice now supports CAGW, I know what I believe as a result.

You even have to hide the link to your dis-information, LYING, CON site that refuses to tell even the most basic truths about Arctic sea ice behind a pseudo-link… just to get people to visit.. PUKE !!!!!!!

Which project is that Jim? Is it the UN sponsored project that denies life saving food and water to innocent humans, you know, the 21,000 people who needlessly die each and every day? Yeah, that’s something to be proud of Jim. Keep crowing.

We have already seen that Jimbo has absolutely ZERO intent on EVER TELLLING THE TRUTH about Arctic sea ice over the full Holocene… choosing to concentrate only on the short period out of the coldest period in the last 10,000 years.

Killer Jim (like all alarmists) just cannot get traction with the public, or traffic at his website, so he comes here hoping to fool fence sitteres. Helping to starve seven million people a year is hard work, and lonely too.
